Samsung AC Error Codes Guide
A Family from Sanghar - June 2006
A family from Sanghar called me in June 2006. They said "Our Samsung AC is showing E1 error. The AC is running but not cooling properly. The display shows the wrong temperature." I asked them to check the room temperature sensor. They opened the front panel and found the sensor was covered with thick dust. They cleaned it with a soft cloth. The error went away. The AC started cooling. The father said "You saved us from the summer heat. Thank you so much."
Error: E1 | Fix: Clean dusty room temperature sensor
Samsung is a leading global brand with a strong presence in Pakistan's air conditioner market. Samsung ACs are known for their advanced technology, digital inverter compressors, and smart features. This guide covers all common Samsung AC error codes with detailed solutions for Pakistani conditions.
Quick Tip: Samsung ACs display error codes on the indoor unit display or through blinking LED patterns. Some models show codes like E1 and E2 while others use combination codes. Always note the exact code before resetting.
A Shopkeeper from Ghotki - August 2008
A shopkeeper from Ghotki called me in August 2008. He said "My Samsung AC is showing E4 error. The outdoor unit is not responding. The AC turns on but no cooling." I asked him to check the communication wire between indoor and outdoor units. He found that rats had eaten the wire. He repaired the wire connection. The error went away. He said "I never thought rats could cause such a big problem. Thank you for your help."
Error: E4 | Fix: Repair damaged communication wire

A Government Employee from Kandhkot - May 2010
A government employee from Kandhkot called me in May 2010. He said "My Samsung AC is showing E6 error. The indoor fan is not spinning. The AC is making a noise but no air is coming out." I asked him to check if anything was blocking the fan. He opened the front panel and found that a piece of plastic had fallen into the fan. He removed it. The fan started working. He said "Such a small thing caused the whole AC to stop working. Thank you for your guidance."
Error: E6 | Fix: Remove obstruction from indoor fan
Detailed Error Code Guide
Error Code E1
Meaning: The sensor that measures room temperature has failed or is sending incorrect signals.
Solutions: Turn off power. Open the front panel and locate the room temperature sensor near the air intake. Clean the sensor gently with a soft cloth. Measure sensor resistance with a multimeter at room temperature. Normal resistance is 5 to 10 kilo-ohms at 25 degrees. If resistance is infinite or zero, replace the sensor.
Error Code E2
Solutions: Disconnect power. Locate the evaporator sensor clipped to the evaporator coil. Check connections and measure resistance. Replace the sensor if it is faulty.
Error Code E3
Solutions: Turn off power to the outdoor unit. Locate the condenser sensor on the outdoor coil. Check connections, which may be corroded from weather. Measure resistance and replace if faulty.
A Businessman from Kashmore - July 2012
A businessman from Kashmore called me in July 2012. He said "My Samsung AC is showing E9 error. The AC runs for 15 minutes and then stops. The outdoor unit feels very hot." I told him to check the outdoor fan. He found that the fan was spinning very slowly. I asked him to check the fan capacitor. He found the capacitor was bulging. He replaced it with a new one. The fan started running at full speed. The error went away. He said "You saved my business from the heat. Thank you."
Error: E9 | Fix: Replace bulging outdoor fan capacitor
Error Code E4
Meaning: Indoor and outdoor units cannot communicate properly.
Solutions: Turn off both units at the circuit breaker for 15 minutes for a complete reset. Check all wiring connections between the indoor and outdoor units. Inspect the communication cable for damage. Look for rodent damage, which is common in Pakistani homes. Ensure connections are tight and free of corrosion. If the wiring is good, one of the PCBs may need replacement. Install a voltage stabilizer for protection.
Error Code E5
Meaning: The compressor is not running properly or the overload protection has tripped.
Solutions: Turn off the AC and let the compressor cool for 30 to 60 minutes. Clean the outdoor condenser coil thoroughly. For non inverter models, check the compressor capacitor. Ensure the outdoor fan is running properly. If the compressor is hot but not running, the overload may be tripped. Wait for it to reset. If the compressor clicks but will not start, the capacitor is likely bad. Compressor repair requires specialized knowledge. Call a certified technician.
Error Code E6
Meaning: The indoor fan motor is not running properly.
Solutions: Turn off power and remove the front panel. Check if the fan rotates freely with no obstruction. Clean the fan blades. Check the fan capacitor with a multimeter. Replace it if faulty. If the capacitor is good, the motor may need replacement.
Error Code E7
Meaning: The outdoor fan motor is not running properly.
Solutions: Turn off power to the outdoor unit. Remove any debris or obstructions. Check if the fan rotates freely. Test the fan capacitor with a multimeter. Replace it if faulty. If the capacitor is good, the motor may need replacement.
A Housewife from Shikarpur - September 2014
A housewife from Shikarpur called me in September 2014. She said "My Samsung AC is showing E5 error. The outdoor unit is making a humming sound but the compressor is not starting." I asked her to check the compressor capacitor. She opened the outdoor unit and found the capacitor was leaking oil. She bought a new capacitor for 450 rupees. She replaced it. The compressor started working. She said "I fixed my own AC. I am so proud of myself. Thank you for teaching me."
Error: E5 | Fix: Replace leaking compressor capacitor
Error Code E8
Meaning: The main control board memory chip has failed.
Solutions: Try a power reset. Turn off the circuit breaker for 15 minutes. If the error continues, the main PCB needs replacement. Contact a Samsung service center.
Error Code E9
Meaning: The system pressure has exceeded safe limits.
Solutions: Turn off the AC and let the pressure equalize for 30 minutes. Thoroughly clean the outdoor condenser coil. Ensure the outdoor fan is running properly. Remove any obstructions around the outdoor unit. If the problem continues, call a technician for a refrigerant check.
Frequently Asked Questions
Pakistan Specific Tips: Install a voltage stabilizer to protect the PCB from power fluctuations. Clean filters every 2 weeks in dusty areas. Check for animal damage to wiring, which is common in many areas. In extreme heat above 45 degrees, it is normal for ACs to run continuously. For professional service, use authorized Samsung service centers.
Safety Warning: Always disconnect power before any inspection. For compressor, refrigerant, or PCB issues, always call certified technicians. Inverter systems have high voltage DC that can be dangerous.
